Lukman congratulates Tanjul because he has won in a competition.

Neyra will wear a white dress to the party. This is the most appropriate choice for a party as dresses are often considered more formal and suitable for special occasions. Additionally, the color white is a classic and elegant choice that is commonly worn to parties.

In response to Sinta's statement that Andini won the Match competition, Amel expresses her surprise and admiration by saying "What a smart girl." This suggests that Andini's victory in the competition demonstrated her intelligence and skill, leading Amel to acknowledge her as a smart individual.

The correct answer is B. "Could you give me some meals." This is the most appropriate response because the speaker is expressing their hunger and asking for food. The word "meals" indicates that they are looking for more than just a drink, which eliminates option A. Option C is incorrect because it suggests that the mother will have to eat, rather than the speaker. Option D is also incorrect because it asks if the speaker wants to eat, rather than requesting food.

Fernando must turn on the lamp at home. This implies that there is a need for light in the house, either because it is dark or because he needs the light for a specific purpose. The other options, such as arriving earlier or keying the door, do not necessarily indicate a specific action that must be taken at home.

Diana's response of "Sure" indicates that she is willing and able to pass the sugar to Mrs. Rosi. This response shows a positive and helpful attitude, suggesting that Diana is happy to fulfill Mrs. Rosi's request.

The correct answer is B. (i) dan (iii).

In option (i), all the pairs have the same second element "m", which means it satisfies the definition of a function where each input has a unique output. In option (iii), all the pairs have the same second element "x", which also satisfies the definition of a function. Therefore, both (i) and (iii) represent mappings (functions) because each input has a unique output.

The given sequence follows a pattern where each term is obtained by subtracting 3 from the previous term. Therefore, starting from 17, we subtract 3 successively to get the next terms: 14, 11, 8, 5, 2. The 7th term can be found by subtracting 3 from the 6th term, which is -1. Hence, the correct answer is C. -1.

Farel should confirm to Neyra a few days before the party if he can't come. This is the best course of action because it allows Farel to inform Neyra in advance and give her time to make any necessary arrangements or adjustments for the party. It shows consideration and respect for Neyra's efforts in organizing the event. Telling the restaurant waiter or sending back Neyra's invitation may not effectively communicate Farel's absence to Neyra, and contacting Neyra's parents may not be necessary or appropriate in this situation.

The given points A(4,2), B(4,7), and C(-1,7) form a right triangle. This can be determined by calculating the distances between the points. The distance between A and B is 5 units, the distance between B and C is 5 units, and the distance between C and A is 7 units. Since the square of the longest side (7 units) is equal to the sum of the squares of the other two sides (5 units each), this triangle satisfies the Pythagorean theorem and is therefore a right triangle. Therefore, the correct answer is B. Segitiga siku-siku.

The missing letter in the pattern is M. The pattern is formed by skipping one letter and then taking the next letter in the alphabet. Starting with A, we skip B and take C, skip D and take E, skip F and take G, and so on. Therefore, the missing letter after C is M.

The correct answer is B. Fernando's mother. This can be inferred from the information given in the question, which states "Who write the message?" The use of the word "write" suggests that the message was written by someone, and the options given are different individuals who could have written it. Based on this, it can be concluded that Fernando's mother is the one who wrote the message.

Alin suggests giving their mother a present as a response to Elin's statement about their mother's upcoming birthday. This shows that Alin is considering the idea of giving their mother a gift to celebrate her birthday.

The underlined expression "Would you like to come to my sister's wedding party next Sunday" is used to invite people. Mr. Jones is being invited to Vicky's sister's wedding party.

Fernando's father will arrive earlier at home. This can be inferred based on the assumption that typically fathers are the primary breadwinners and may have a more structured schedule, allowing them to leave work earlier and arrive home before other family members.

The point K is given to be (7, a). It is mentioned that K is 7 units away from the y-axis and 6 units away from the x-axis, and it is located below the x-axis. This means that the y-coordinate of point K is negative. Since K is 7 units away from the y-axis and below the x-axis, the y-coordinate must be -7. Therefore, the value of a is -7.

Fernando will hold his party in the evening. This is the most logical time for a party as it allows for guests to attend after work or other commitments. Holding the party in the morning or afternoon would likely interfere with people's schedules, while holding it at midnight would be too late for most people. Therefore, the evening is the best option for a party.

The given information states that Lenita bought 1 kg of beef and 2 kg of chicken for a total of Rp 164,000, and Pipit bought 3 kg of chicken and 2 kg of beef for a total of Rp 296,000. Let x represent the price of 1 kg of beef and y represent the price of 1 kg of chicken. The equation for Lenita's purchase can be written as x + 2y = 164,000, and the equation for Pipit's purchase can be written as 2x + 3y = 296,000. Therefore, the correct answer is B. x + 2y = 164,000 and 2x + 3y = 296,000.

The question states that a rope is cut into five pieces, forming a sequence of numbers. The shortest piece is 10 cm, the middle piece is 20 cm, and the longest piece is 30 cm. To find the initial length of the rope, we need to find the common difference between the lengths of the pieces. Since the lengths form an arithmetic sequence, the common difference is the difference between any two consecutive terms. The difference between the middle piece (20 cm) and the shortest piece (10 cm) is 10 cm. Therefore, the common difference is 10 cm. To find the initial length of the rope, we need to subtract four times the common difference from the longest piece. 30 cm - (4 * 10 cm) = 30 cm - 40 cm = 100 cm. Therefore, the initial length of the rope is 100 cm.

The cost of 4 sabun A and 2 sabun B is Rp 34,000. The cost of 3 sabun A and 1 sabun B is Rp 23,000. To find the cost of 5 sabun A and 3 sabun B, we can calculate the cost of 1 sabun A and 1 sabun B using the given information. The cost of 1 sabun A is Rp 34,000/6 = Rp 5,666.67. The cost of 1 sabun B is Rp 11,000/2 = Rp 5,500. Adding the cost of 5 sabun A and 3 sabun B, we get Rp 5,666.67*5 + Rp 5,500*3 = Rp 45,000. Therefore, the answer is C. Rp 45,000.

The given function is f(x) = ax + b. We are given that f(-3) = -15 and f(3) = 9.

To find the values of a and b, we can substitute the given values into the function.

For f(-3) = -15, we have -15 = a(-3) + b.
And for f(3) = 9, we have 9 = a(3) + b.

Solving these two equations simultaneously, we can find the values of a and b.

Multiplying the first equation by 3, we get -45 = -3a - 3b.
Adding this equation to the second equation, we get -36 = -6b.
Dividing both sides by -6, we find that b = 6.

Substituting this value of b into the first equation, we get -15 = -3a + 6.
Simplifying, we find -3a = -21, so a = 7.

Now that we have the values of a and b, we can find f(-2) and f(2) and add them together.

f(-2) = 7(-2) + 6 = -14 + 6 = -8.
f(2) = 7(2) + 6 = 14 + 6 = 20.

Therefore, f(-2) + f(2) = -8 + 20 = 12.

So, the correct answer is A. -6.

The given system of equations can be solved using the method of substitution or elimination. By solving the first equation for x, we get x = 5 + 3y. Substituting this value of x into the second equation, we get 3(5 + 3y) + 2y = 4. Simplifying this equation gives us 15 + 9y + 2y = 4. Combining like terms, we have 11y = -11, which implies y = -1. Substituting this value of y back into the first equation, we find x = 5 + 3(-1) = 2. Therefore, the solution to the system of equations is (2, -1).

The given pairs in the relation {(1, 2), (2, 4), (3, 6), (4, 8), (5, 10)} show that each element in G is half of the corresponding element in H. Therefore, the relation from set G to set H is "setengah dari" which means "half of" in English.

The equation of a line passing through two points can be found using the formula (y - y1) = m(x - x1), where m is the slope of the line. By substituting the given points (-2, 1) and (3, 5) into the formula, we can find the slope of the line. The slope is (5 - 1) / (3 - (-2)) = 4/5. The equation can be rewritten as 5(y - 1) = 4(x - (-2)), which simplifies to 5y - 5 = 4x + 8. Rearranging the equation, we get 4x - 5y + 13 = 0, which matches option A.

The correct answer is "spent" because the sentence is in the past tense and refers to a completed action. "Spent" is the past tense form of the verb "spend," indicating that Fadil and Rajata already completed their holiday together.

The perimeter of a rectangle is equal to twice the sum of its length and width. In this case, the perimeter is given as 72 m, and the difference between the length and width is given as 4 m. Let's assume the width is x. So, the length would be x+4. The perimeter can be expressed as 2(x+(x+4)) = 72. Simplifying this equation, we get 4x + 8 = 36, which gives us x = 7. Therefore, the length is 7+4 = 11. The area of the rectangle is equal to its length multiplied by its width, which is 11*7 = 77. Hence, the correct answer is D. 320 m2.
